1 Energy Delivery Efficiency Performance Measures

a) Load factor
Percentage of electrical energy entering the transmission system over maximum demand times hours per year

                        68.05%          68.95%

b) Loss ratio
Transmission losses over energy entering the system

                        6.16%           6.09%

c) Capacity utilisation
Maximum demand over total transformer capacity

                        70.53%          66.91%
